The measure of the third angle of a triangle is 23.2° .
How to find the third angle of the triangle in the question?
We know that sum of the interior angles of a triangle is always 180° .
The two angles given is 109.7° and 47.1°.
Let the third angle be x°.
⇒ x + 109.7° + 47.1° = 180°
⇒ x + 156.8 = 180°
∴ x = 23.2°.
Therefore the measure of the third angle is 23.2°.
